National Program for Inspection of Non-Federal Dams. Staffordville Reservoir Dam (CT 00333), Thames River Basin, Staffordville, Connecticut. Phase I Inspection Report.
Abstract
The Staffordville Reservoir Dam is a stone masonry dam that is 525 feet long with a 125 foot spillway. It has a gate house with a 30 inch diameter discharge pipe which can be routed through the adjacent Schwanda Button Factory or to the downstream channel. The dam is classified as intermediate in size and has a high hazard potential based on downstream habitation. Based on visual inspection, records available at the site and past operational performance, the dam is judged to be in poor condition. There is no engineering data available, however, there are areas of concern that should be corrected or investigated further as to their effect on the integrity of the dam. The east bank of downstream side of the dam shows a significant amount of water flowing from the ground that appears to be caused from a broken pipe in the lower gate chamber. This condition should be investigated further, because it could be a potentially dangerous condition. The project will pass only 28 percent of the routed test flood peak outflow before overtopping the dam.
